Help me convince DH we need another tent...

We currently have 3 tents for various camping needs. However we now have DD to consider!

For ordinary camping we're fine, taking our big Outwell - we all fit in nicely with all our equipment, but it's too big and cumbersome for a festival. For festivals we used to take our smaller outwell, however this being a 3 man tent we can't fit me, DH and DD along with the few bits of equipment and clothes we need for the festival. We have a medium sized 4 man tent that is big enough for us and the festival... however the 2 bedrooms are at opposite ends of the tent and not joined by a removable wall. All three of us can't fit in one bedroom. DH says it'll be fine and he'll sleep in one bedroom and me and DD can sleep in the other.

BUT, I'll miss our quiet whispered nighttime and early morning conversations, not to mention miss his body heat . So I would like to add another tent to our collection. Just a cheap 5 man vango that has one large bedroom and a good sized porch. How can I persuade him to part with £70 for this new tent?!

Can't . We're coming back from week long holiday in Pembrokeshire on 22nd. Just bad timing otherwise I would! Might pop down and see you all though - will head towards bell tents with twinkling lights on

Flamingo? Sell tents? Not sure I could part with them... but now you mention it, that could be just the compromise I need! However DH might see through the 'I'll sell the old ones on ebay' comment as he hears it regularly (guitars, mobile phones etc etc, all clogging up cupboards and the loft as I can't part with them/can't get off my bum and get them listed!).

I am imagining striding purposefully for a prettily decorated bell tent and marching up to the woman who looks like she owns it and saying 'hello, are you Riven?'. And then getting a blank stare as I realise I'm at the wrong FoD campsite

Not sure I am brave enough to do camping on my own with the girls and lots of people I don't know (yet) even though I know they're very nice!
